TRACTION-WHEEL.-

SPECIFICATION forming part of Letters Patent No. 543,075, dated July 23,1895.

Application filed December 1, 1894. Serial No. (No model.)

To aZZ whom, it may concern:

Be it known that I, GUs'rAF ARVID ANDER- SON, a subject of the King ofSweden and Norway, residing at Waynesborough, in the county of Franklinand State of Pennsylvania, have invented certain new and usefulImprovements in Wheels, and I do hereby declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to the driving-wheels of traction or roadengines; and it consists I in the construction of the rim of the wheel,ashereinafter fully described and claimed, permitting the wheel to workwith equal advantage upon hard and soft roads without slipping orsinking.

In the drawings, Figure 1 is a side view of cross-section through therim.

A is the rim of the wheel, which is formed of a series of similarsections A. These sections are securely riveted or otherwiselsecured totwo rings B, one at each edge of the wheel. Each section A has a rib I),preferably arranged to come at the middle of the wheel. The ribs I) makea circumferential ring around the wheel and are preferably provided withsmall cross-grooves, so that the ring may be better enabled to run onhard ground without slipping.

D are a series of laterally-arranged ribs, and C are pockets between theribs. The tops of the ribs D are level withthe top of the rib b, and thepockets C have downwardly and outwardly inclined bottom portions 0.

E are pockets on the under side of the sections A .for the reception ofthe endsof the spokes E, which are preferably of wood and are secured'to the hub of the wheel in any approved manner.,

F is a cross-rib between the pockets E, on the under side of eachsection, for the purpose of stiffening it; but this rib may be left out,if desired. H

The ribs D are preferably hollow on their Fig.2 is a under side, and allparts of each section are made of as nearly equal thickness as possible,so that the sections can be made of cast-steel or cast malleable ironand not suffer distortion from shrinkage in manufacture.

The rivets g, which join the sections to the countersunk holes in thebottoms of the pockets C, and the ends of the sections are preferablyarranged to overlap each other, so that they are rigidly securedtogether as well as to the rings B.

The ribs D may be arranged crosswise of the face of the wheel, as shown,or they may be arranged diagonally or spirally on its face. The sides ofthe ribs D are preferably inclined, as shown in Fig. 1, and they may becurved like the teeth of a toothed gear-wheel, if desired. The sides ofthe'ribs D may also be inclined laterally, if' desired, so that the ribsbecome wedge-shaped; and the form of The bearing-surface of the wheel,when in contact with the soft road, is greatly increased, and the wheelis thereby prevented from sinking. The inclined bottoms of the pockets,together with the inclined sides of the ribs and the absence ofprojecting rivetheads, permit the wheel-rim to clear itself as it passesover the road, and the dirt does not accumulate in the pockets andadhere in large quantities to the rim. v r

"Vhat I claim is 1. A wheel rim provided with a circumferential rib,lateral ribs on each side thereof, and pockets formed between thelateral ribs and having their bottom portions inclined downwardly andoutwardly in opposite directions upon opposite sides of theeircumferenets on its periphery for engaging with the surtial rib,whereby the tread of the wheel enface of the road, substantially as setforth. to gages with the surface of a road to a greater In testimonywhereof I affix my signature or less extent proportionate to thesoftness of in presence of two witnesses.

5 the surface, substantially as set forth. GUSTAF ARVID ANDERSON.

2. The combination, with the two support- \Vitnesses: ing rings B, ofthe wheel rim secured to the HERBERT W. T. JENNER, said rings andprovided with ribs and pock- DANIEL S. BEARD.
